... A new kind of environmentally friendly filter paper based on ultralong hydroxyapatite nanowires (HAPNWs) and cellulose fibers (CFs) with excellent filtration and adsorption properties has been developed for the application in high-performance water purification. The use of polyamidoamine-epichlorohydrin (PAE) resin increases the wet mechanical strength of the as-prepared HAPNW/CF filter paper. The ...

... Designing a unique electrochemical interface to exhibit Pt-like activity and good stability is indispensable for the efficient hydrogen evolution reaction (HER). Herein, we synthesize well-defined Mo₂C@NC@Pt nanospheres with a sandwich-structured interface through a facile organic–inorganic pyrolysis and following reduction process. The obtained Mo₂C@NC@Pt heterostructures with ultralow Pt loading ...

... The emerging ubiquitous flexible/wearable electronics are in high demand for compatible flexible/high-energy rechargeable batteries, which set a collaborative goal to promote the electrochemical performance and the mechanical strength of the fundamental flexible electrodes involved. Herein, freestanding flexible electrode of Si/graphene films is proposed, which is fabricated through a scalable, zi ...

... Gold nanorods (GNRs) and doxorubicin (DOX) were loaded into the lumen of halloysite nanotubes (HNTs) via a rapid synthesis process (2 min) and physical adsorption. The targeting molecules of folic acid (FA) are then conjugated to HNTs via reactions with bovine serum albumin (BSA). The formation of GNRs in HNTs was verified by different techniques. Au-HNT-DOX@BSA-FA shows a maximum temperature of 2 ...

... A nanothin block copolymer (BCP) brush-layer film adsorbed on glass nanofibers is shown to address the long-standing challenge of forming a template for the deposition of dense and well-dispersed nanoparticles on highly curved surfaces, allowing the development of an improved nanosensor for neurotransmitters. We employed a polystyrene-block-poly(4-vinylpyridine) BCP and plasmonic gold nanoparticle ...

... Efficient and safe intracellular delivery of proteins is highly desired in the development of protein therapeutics. Current methods of protein delivery commonly suffer from low loading efficiency, low stability in serum, and lack of versatility for different proteins. Here, we developed a platform for efficient protein delivery using mesoporous silica nanoparticles (MSN) with lipid fusion. By diff ...

... Rechargeable lithium–sulfur batteries are potential candidates for storing electrochemical energy because of their extremely high energy density. However, their practical applications are prohibited by the sluggish charge transfer, the retarding Li ion diffusion, and the shuttle effect of lithium polysulfides. We report here a high-performance cathode material in which a S submicrosphere with a ma ...

... One-dimensional microstructure has been regarded as one of the most desirable configurations for magnetic carbon-based microwave absorbing materials (MAMs). Herein, pea-like Fe/Fe₃C nanoparticles embedded in nitrogen-doped carbon nanotubes (Fe/Fe₃C@NCNTs) are successfully prepared through a direct pyrolysis of the mixture of FeCl₃·6H₂O and melamine under inert atmosphere. The chemical composition ...

... Expediting the wound-healing process is critical for patients chronically ill from nonhealing wounds and diseases such as hemophilia or diabetes or who have suffered trauma including easily infected open wounds. FDA-approved external tissue sealants include the topical application of fibrin gels, which can be 500 times denser than natural fibrin clots. With lower clot porosity and higher polymeriz ...

... Microgel loading with inorganic nanoparticle (NP) composites attracts interest for various biomedical applications. However, the encapsulation of NPs into microgels usually is a diffusion process driven by osmotic pressure, which depends highly on the concentration of NPs and causes low loading efficiency. In this work, we demonstrate preparation of microgels with ultrahigh content of various nano ...

... Si has been recognized as a next-generation anode alternative to graphite for high-energy-density lithium-ion batteries. However, the most intractable problem of previous Si-based anodes is the relatively low compressive strength of particles because of excess voids and porous structures, thus leading to poor structural integrity and electrochemical performance under high pressure of the rolling p ...
